- This patch brings over a few features from MirBSD:
- * -fhonour-copts
- If this option is not given, it's warned (depending
- on environment variables). This is to catch errors
- of misbuilt packages which override CFLAGS themselves.
- * -Werror-maybe-reset
- Has the effect of -Wno-error if GCC_NO_WERROR is
- set and not '0', a no-operation otherwise. This is
- to be able to use -Werror in "make" but prevent
- GNU autoconf generated configure scripts from
- freaking out.

-I talked to Andrew about what files he changed in GCC and created and

-files in glibc but I don't see any use of '.section .note.GNU-stack' in
-any assembly files in glibc (for any platform) so I wasn't planning on
-creating a glibc to add them to mips glibc assembly language files.
